Polymer concrete Industrial Baseboards

Industrial Baseboards Definition

Baseboard is a prefabricated lining part which is placed perimetrally over the wall and adjoining the ground. It is intended to be shock-resistant and provide hygiene protection.

ULMA baseboards protect the wall, waterproofing and rounding off the joining of the wall to the ground. They are hygienic and suitable for the food industry, complying with HACCP standards.(Hazard Analysis and Critical Control Points).

They are capable of eliminating any joint between the ground and the wall, keeping food accumulation to a minimum. In this way bacterial growth is avoided, making the cleaning of this area speedier and simpler.

Industrial Baseboards Models

We have 11 models, which vary in size and protection level are available in two designs: short-leg and recess.

Half-round design: Its lowest visible part forms a half-round angle between the wall and the ground to meet EC standards..

Recess: They have a recess of 10 or 15 mm so they can be installed above an existing half-round in the ground covering

Select yours in line with theProtection Level, height and design you require.

Industrial Baseboards Protection Level

In the food and pharmaceutical industry quality and hygiene are of paramount importance. Harsh working conditions (dense traffic, intense work rate, ground humidity) speed up the deterioration of walls and corridors,

making ULMA baseboards the perfect protection from trolleys, pallet trucks and forklift trucks. We have 4 protection levels which we have set out below:

FAQ

1. Why is polymer concrete ideal for use on new building and restoration work?

a. Because it is waterproof, thus ensuring watertightness.

b. Because it is highly resistant and has great durability.

c. Because it is shapeable and can thus take all kinds of shapes and sizes.

d. Because it is light and allows better performance at the works site.

2. How does polymer concrete react to carbonation?

a. Polymer concrete does not have the typical cabonation pathology in which interior reinforcements are oxidised and the concrete breaks; firstly, because it is a non-porous concrete and secondly because it never has interior reinforcement as it does not need to be thanks to its hardness and resistance.

3. How does pollution affect polymer concrete?

a. Polymer concrete affords very high resistance to chemicals and the various external agents and consequently its physical properties are not affected by pollution.

4. Can severe frosts break polymer concrete?

a. No. Polymer concrete is a non-porous concrete; consequently, it does not allow the entry of any water which could expand upon freezing and actually burst or break it.

5. Is the correct installation of polymer concrete complicated?

a. Not at all, but various aspects need to be borne in mind. Polymer concrete is made up of polyester resins and silica aggregates and its expansion coefficient is thus greater than traditional works' materials. This means great care needs to be taken when installing and selecting the bonding materials.

6. What needs to be borne in mind to ensure correct installation?

a. Choice of appropriate bonding materials. In places where there are major temperature variations, it is particularly recommended to use elastic adhesive mortars to ensure greater bonding and absorption of the expansion movement.

b. Use of the mechanical anchorages provided with the parts. Polymer concrete prefabs are supplied with mechanical anchorages embossed in putty for introduction into the bonding adhesive mortar. This ensures proper securing.

c. Placement of expansion joints. 5 mm expansion joints must be ensured between parts to absorb their movements. The joints must be sealed with an appropriate material to ensure the watertightness of the whole.

7. Which bonding materials must be used to ensure correct installation?

a. You are recommended to use elastic adhesive mortars capable of absorbing the movement produced by the expansion-contraction of the polymer concrete.

8. What is the right material for sealing joints?

a. You are recommended to use silicones with a high elasticity module, resistance to the elements and high stability under UV rays to prevent it from going yellow.

Step-by-step

Installation of Copings

3Open the anchorages at the back of the parts, introducing them into the installation area stern or chamber

5Install the piece, fitting the piece in place, levelled and aligned.

7Place the next part alongside the joints. Hammer, level and align the part in accordance with the position of the first part.

9Seal the joints using a highly-adherent flexible, impermeable element with modulus of elasticity. It is highly recommended that this element should have good resistance to UV rays to avoid yellowing and quartering.

2Apply a layer of elastic adhesive cement both in the installation area and on the part.

4Apply a coat of elastic C2S2 type adhesive mortar to the coping (dual adhesion). Make sure that the adhesive mortar covers and surrounds the anchor.

6Whenever more than one part needs to be installed, present the joint alongside the installed part, marking the 5 mm joint between the parts.

8Clean the existing joint between the parts using the master piece itself, sliding the latter to the exterior and making sure that said joint fits smoothly throughout its thickness.

Step-by-step

Installation of Window Sills

1Point and extract the first brick from each lateral of the hole where the window sill has to be built in.

3Open the anchors on the rear of the parts, one pin on each side.

5Install the piece, fitting the piece in place, levelled and aligned.

7Whenever more than one part needs to be installed, present the joint alongside the installed part, marking the 5 mm joint between the parts.

9Clean the existing joint between the parts using the master piece itself, sliding the latter to the exterior and making sure that said joint fits smoothly throughout its thickness.

2Generate a support slope using mortar which is very rich in cement so that it is a resistant surface in the area on which the part is to be placed.

4Apply a coat of elastic C2S2 type adhesive mortar to the window sill (dual adhesion). Make sure that the adhesive mortar covers and surrounds the anchor.

6Leave a joint of at least 5 mm between the part and the brick on both sides. The placement of two around 1 cm thick strips of Porexpan can be used both as a gauge and as a joint as it has sufficient deformation capacity.

8Place the next part alongside the joints master piece. Fit the part in and level and align it.

10Seal the joints using a highly-adherent flexible, impermeable element with modulus of elasticity. It is highly recommended that this element should have good resistance to UV rays to avoid yellowing and quartering.

Step-by-step

Sealing instruction

1A wet cloth cannot be used to clean the joint, the appropriate method would be to blow on the joint.

2Place the joint bottom(polyethylene cordon whose diameter is slightly greater than the width of the joint to be sealed) which limits the sealing depth and prevents the adherence of the sealing product to the bottom of the joint. Failing that, an antiadherent film may also be used.

3Clean the lateral faces of the joint with Sika Primer 215.

4Apply the polyurethane filler. (Sikaflex Pro 2 HP or similar)

IMPORTANT INFORMATION:
All orders are given with the installation instructions and the required number of master pieces for creating joints.

Secure the lintel to the upper floor or any resistant element, using L-shaped stainless steel splints (see Fig.2). The splint is screwed to the lintel nuts and at the other end it is screwed to the floor.

It is recommended to carry out this operation at all the anchorages which the lintel has.Note: the splint must have a oval hole in the lintel part owing to the possible excentricity with regard to the position of the lintel anchorages.

Model DCInstructions for Installation of Lintels (Breastsummers)

1

Place the lintel (breastsummer) on the attendant spun brick, supporting it on the facade around 12 cm on each side (recommended) (See Fig. 1)

Place a mainstay at the centre of the opening with a view to achieving the proper levelling thereof. (see Fig.2)

The lintel has galvanised anchorages every 50 cm with perforations.

2

Secure the breastsummer anchorage to the upper floor or any resistant element by means of a metal strap or steel wire. Tighten the strap or twist the wire until a precamber has been created at the centre of the lintel opening which will force us to re-position the mainstay. (see Fig.3)

It is recommended to carry out this operation at all the lintel anchorages.

3

Once the lintel has been secured, the façade is continued above the latter.

Once the lintel has been loaded and the minimum time has elapsed for the drying or setting of the elements involved in the construction of the façade, the mainstay is removed.

Lintels with one end as projectionThe same procedure is followed as in previous sections, but we should bear in mind that at the end where we have the part in projection we must provided an anchorage to tie and/or secure it. In the event that the lintel does not have an anchorage at the end, this will be created at the works site by means of an expansion anchor.

Step-by-step

Installation of Slab Faces

1Prepare a base to serve as a frentes. support and alignment of the facades to be installed.

3Cut the threaded rods to the desired measurement (it has to enter at least 5 cm into the wrought iron with healthy concrete). Screw the rods to the bushings on the back of the facade.

5Fill the boreholes made with a chemical anchor (this must be carried out bearing in mind the curing times for the anchor specified by their manufacturer).

7Place the following parts, aligning them perfectly and foreseeing a joint between them of at least 3 mm.

2Carry out an anchor position template, taking one of the facades as a model.

4Apply a coat of C2S2 type elastic adhesive mortar to the upper horizontal part in order to set in place the piece support.

6Insert the piece using the anchors and take it to the base we have prepared previously, leaving it plumb horizontally and vertically.

8Seal the joints using a highly adherent flexible material to avoid any water leaks. It is highly recommended that said material should have good resistance to UV rays to prevent its yellowing and quartering.

Light material which facilitates the handling and installation at the works site.

Waterproof material which avoids the need to install damp-proofing sheets to comply with the standards of CTE compared with other materials where their use is necessary.

Polymer concrete Advantages

Compressive strength
Polymer concrete applied to prefabricated systems can withstand over 30.2 MPa of compressive strength, compared with the 7 MPa which traditional concrete can bear before breaking or cracking.

Resistance to chemicals
Polymer Concrete has been shown to be one of the most resistant materials to any kind of chemical. And its components do not react on contact, avoiding product disaggregation or deformation.

Remains unchanged in freezing and thawing cycles
Contrary to traditional materials, this one is not affected by freezing and thawing cycles, avoiding the appearance of fissures or cracks and keeping all its physical properties intact.

Resistant to shock and abrasion
As Polymer Concrete is a compound material, this ensures the perfect upkeep of the surfaces without any perception of wear and tear owing to usage or the passage of time.

Lightness
Thanks to its excellent mechanical properties, it allows parts with a finer profile to be made, contributing to the lightness of the latter. Lightness which becomes savings by reducing the use of auxiliary means of transport to the works site.

Abrasion wear and tear
The hardness of the silica aggregates ensures the good upkeep of those surfaces exposed to wheeled traffic owing to the polymer concrete's optimum resistance to abrasion.

Aesthetic and colour options
As they are manufactured with moulds, they afford great freedom in terms of design. This allows parts to be adapted to the requirements of each project and the criterion of the architect. The lightness of the parts affords a new architectonic aesthetics concept for building facades.

Ideal for fluid run-off
The polymeric nature of this material allows smooth surfaces with very low friction on prefabricated elements, thereby facilitating the rapid run-off of fluids and also offering a water absorption index which virtually non-existent, compared with 5-10% with traditional concrete.
